I have a wireless internet connection and whenever I use Steam it usually cuts off. Plus whenever I use Bit-torrent it generally cuts off too. I moved closer to my router but it still happens. I heard that there is some connectivity issues already in Ubuntu 13.04 but I never found an answer to resolve it.
I heard you need this so here you go.

what you can do is check if your wi-fi card does need a (sort of) driver.
because ubuntu uses one driver for all kind of cards.
i had to do this on my asus n55sf laptop.
you have a rtl8191SEvA card from Realtek
the download click here

choose the second linux table because this one is for the rtl8191SEvA card.
